I can totally relate to the things the author wrote on the post, and my personal experience is not much different. However, I can't help but feeling a little bit uncomfortable with the tone.

As developers / engineers we are privileged to be in a position to choose our employer more than they choose us, to be "chased" by recruiters and flattered about our much desired skills. It's important to maintain some humility and not forget how hard it is for other people (recruiters included).

I have no doubts that the author didn't intend to patronize and that his advise to recruiters is ultimately a positive one, (yes - it would save both the recruiter and the engineer time, if the recruiter wouldn't call about a java job when the CV says javascript). I just wish it was coming across a little less arrogant.
